TRACK SUPPORT.

Application filed December 18, 1923. Serial No. 681,421.

fo ai? 'icio/n it may concenn:

Re it known that I, VILBERT NELSON EL- iJo'r'r, a snhject ot the King ofGreat Britain. and a resident of the city of Hamilton, in the count),vof TVcntworth, in the Province otl Ontario, Dominion of Canada, haveinvented certain new and useful Improvenicnts in Track Supports, ofwhich the folowing the specitication.

Mv invention relates to improvements in track siii'iports with moreparticular reference to devices tor supporting overhead tuhular trackssuch as are used t'or door hangers. overhead trolleys and the like. andthe ohiect ot the invention is to provide an imiliroveil torni otcon'ibined coupling and hanger support for this purpose which willsiinplitv and lower the cost of manufacture as well expedite the work oterecting these tracks.

liv invention consists of the construction and arrangement ot parts allas hereinafter more particularly described and illustrated in theaccompanying drawings in which Fig. t is a central longitudinal sectionshowing two sections of tubular overhead tra coupled and supportedaccording to in); invention. the section being taken on the line l. lVof Fig. f2.

Fig. l is a transverse section on the stag- ;fjcrcd line Q of Fig. l.

,ifi-i1'. f is a plan view ot Fig. l.

YVig. -tA is a perspective view ot a peculiar T-shaped holt used in myinvention.

Fig. 5 is a fragmentary view of the end oiP au overhead tubular tracksection with which inv invention 1s used.

Fig. tl is a diagrammatic view of an overheat t ihular t ack connectedand supported f ing to my invention.

in the drawings like characters ot reterence indicate correspoin'lingparts in the dit tcrciit views.

t are overhead tubular track sections which have the longitudinalopening 2 4therein at'ter the usual practice.

it cach cnil ot' each track section l is neil a longitudinal recess orslot 3, said slots heing situated diainetricallv opposite to thelongitudinal opening Q in the track -cction tis a tuhnlar couplingineinhcr having the linigituilinal opening 5 therein. The

inside diameter of this coupling meuiher l is equal to the outsidediameter of the track sections l.

hanger lirackct ti is secured to the coupling inemher 4 h v rivetsl Tthe inner heads S ot these rivets heing countersunk flush with theinterior peripherjvv ot the coupiing n'ieinher 1l.

t? is a holt extending through aligned orifices lt) in the nienihcrs -land (i, said oiiticc l() heing lo lated diamctricallf,Y opposite to theoiliening 5 and centrallvv ot he length of the cinipling inen'iher 4.

rI`his holt il is provided with a peculiar elongated T-shapcd head lland carries a nut l2 at its ontcr end.

The construction and operation ot' inv invention is as follows.

lt will he ohserved (see Fig. l) that the ends ot' adjacent tracksections l telescopicall)v engage within the coupling nicnihcr t and.since the rivet heads t? are countersunk and made liush with theinterior pcriphervY ot' this coupling nieuiher. the track sections ma)Ylne siid into the coiipling.

lllhen the unt 'l2 has hccn tightened upon the holt 9. the, T--shaiiedhead llV is drawn against the y'ntericr tace of the couplin',y memher -tand forms a longitudinal. elongated protnherance projecting from their.- terior periphery of the member 4.

The coupling of two adjacent track sections 1 is thus accomplished hysimpl)v inserting the ends thereof within the coupling niemher 4.

In this operation the track sections niust he turned so thaty the "headll. of the holt Si passes into the slots oi' recesses 3.

This engagement ot the head ll within the slots 3 positivelyv insuresthe exactlyY correct alignment ot' the track sections, so that thelongitudinal openings 2 in the sections are in proper alignment andtherefore, when once assemhled it is iinpossihle for the sections tohecome displaced to throw the oilienings 2 out of alignment.

ln the drawings a supporting structure to which the hanger hrackets (iare secured is indicated at'. 13.

This supporting structure is indicated in ln'oken lines in Figs. l and land in tull lines in Fig.

lllhcu comparatively short track sections tif) are used the couplingsjoining adjacent track sections will also provide Sufficient support forthe track but in the case of long sections it will be necessary toprovide supports at points intermediate of the length of these longsections.

In Fig. G at A Ais indicated a` short track section in which the endcouplings provide sntticicnt support while at B is indicated a longsection requiring the intermediate supports (l.

Ordinarily a special form of intermediate support must be provided sincethe end couplings as hitherto made will not slide along the track.

Vith my construction however the same type of support may be used bothas an intermediate support and an end coupling and thus thenuinufacturing cost is considerably reduced since only one torni ofsupport need be made.

dien the support is to be used as an end coupling the T-headed bolt llis inserted but when used as an intermediate support this bolt isomitted and it will be noted that, in this case, there being noprotuberance on the interior ot' the member 4 this men'iber may be slidalong the track to any desired position.

ln Figs l and 2 the partially slackened bolt S) is indicated in brokenlines.

From the foregoing it will be clear that I have devised valuableimlnovements in track supports ot the class described which will greatlyexpedite the manufacture and erection of these tracks as well aspositively insuring proper alignment.

Vilhat l claim as my invention is:

l. rllhe combination with a tubular track ot a coupling there't'or, theinner periphery of the coupling contorn'iing to the outer periphery otthe track and slidable longitudinally thereof, and a protuberancedetachably associated with the coupling and projecting from its innerperiphery.

2. The combination with two tubular track sections to be connected, ot atubular coupling telescopically engaging the adjacent ends of saidsections, and a protuberance detachably carried by the coupling andprojecting beyond the periphery thereot, said protuberance adapted toengage within recesses formed in said adjacent ends of the tracksections.

3. The combination with two tubular track sections to be connected, of atubular coupling telescopically engaging the adjacent ends of saidsections, and a longitudinally elongated protuberance detachably carriedby the coupling and projecting beyond the periphery thereof, saidprotuberance ,adapted to engage within recesses formed in said adjacentends ot the track sections.

4. The combination with two tubular track sections .to be connected, ofa tubular coupling telescopically engaging the adjacent ends ott. saidsections, a bolt mounted in the coupling, and an elongated T-shaped head`on said bolt .situated within the coupling, said T-shaped head yadaptedto engage within recesses itormed in said adjacent ends of .the tracksections.

A coupling and support for overhead tubular tracks comprising, a tubularcoupling men'iber, a protuberance detachably associated with theinterior periphery thereof and a hanger bracket .carried by saidcoupling member.

A coupling and support for overhead tubular tracks comprising a tubularcoupling member.y a hanger bracket carried thereby, a bolt extendingoutwardly through an orilice in the .coupling member, and an elongate-,dT-shaped head formed on the bolt and forming a protuberance projectingfrom the inner periphery of the coupling member.

7. A coupling and support for overhead tubular tracks comprising atubular coupling member having a longitudinal opening' therein, a hangerbracket secured to the exterior ot said coupling member, said couplingmember provided with an oriticc therein at a point diametricallyopposite the a toresaid opening and centrally of the length of thecoupling, a bolt mounted in said oritice, and an elongated Tshaped headformed on said bolt, said head forming a protu herance projecting fromthe inner periphery oit the coupling.
